TO ALL WHOM 1T MAY CONCERN: i

Be it known that I, A. M. CuLvnR, of Bedford, in the county of'Cuyahogu., and Stute of Ohio, have invent-ed certain new and useful Inproveme'nvts in Lifting-Jacks; and I do hereby declare that the following is-a full and complete description ol' the construction and operation of' the same, reference being had to the accompanying drawings, making a part nf thisl specification, in which- Figure 1 is a side view of the jack.

Figure 2 is a front end view of' the same.

Lilie letters of reference rel'er to like parts.

This jack consists of' `the beam or lever A, ig.,1,wl1ieh may be of any convenient size and length, and of" the shape expressed in the drawing. The edge of the larger end of the lever is faded with iron in order to prevent abrasion and to give additional strengthto the end. B and B are n. pair of adjustable standards or legs pivoted to the lever nt the point C, the lower end ofwhich is-nrmed with a sharp iron point, D, the purpose of" which will be hereafter shown.

The manner or" using this jack is as follows: It` is placed under the axle nenr the wheel so that it may rest upon the section oi' the lever between the legs at'the point x; the legs are then spread out as shown in the drawing; On raising up the longarni of the lever, the front legs B become the fulerum of leverage; in conse'- quenee Oi' this lifting up of the arm, the legs B are brought or swung .nearer together Or towards a vertical position; on depressing the arm the legs `B become in turn the fulcrum, und legs Bare thereby drawn together as were the legs B'; and so on altcrnately,.nt cach reverse action of the lever, the legs approach each other and thus raise up the wheel until they Obtain a vertical position, as shown in fig. 2 and the dotted lines fig. 1, in which position they support the axle and wheel thus raised. The points D referred to prevent the legs from slipping` upon the ground when spread out for the purpose ofrlii'ting, and thereby giving greater security to the imple ment. In order to shift'the jack the .lever'is depressed or raised, and the pair of legs, thus .relieved of the weight of the axle and wheel, are drawn out from a. vertical posit-ion and the wheelV theneomes to the ground. The construotion of this jack is such as to adapt itself readily to any kind Ol' wagon or carriage, to the front axle as well as to the hind one, and that without the necessity of removing any pin or bolts for `the purpose of Obtaining the proper height oi' the jack sothat it maybe placed under the axle.

What I claim as my improvement, and desire to secure by Letters Patent, isl The arrangement of the legs B B', pivoted to and in combination with the lever A, in the manner and for the purpose described. v A. M. CULVER.
